REPORT HIGHLIGHTS

The Federal Reserve changed its key interest rate five times during the course
of the Fund's fiscal year in response to a worldwide economic dislocation and,
later, signs of recovery and stability.

We effectively used mortgage-backed securities to maintain a high level of
current income for the Fund.

PRESIDENT'S LETTER

Dear shareholder,

In many ways, the 1999 investment environment has, so far, unfolded as many
expected it would, producing both attractive opportunities and formidable
challenges for investors.

      On the economic front, early worries about the effects of global weakness
in the wake of last year's credit and currency crises have abated. Instead, as
many economies around the world begin to strengthen, concerns now center around
whether the U.S. economy may be growing too quickly. Throughout the year,
consumers in the United States have continued to spend and borrow heavily, more
than offsetting any temporary slowdown in the industrial and export sectors.
      The economy's strength has not gone unnoticed by the nation's monetary
policymakers. In an effort to ward off emerging inflationary pressures, the
Federal Reserve Board increased short-term interest rates this past summer.
      Market reaction to robust economic growth has been mixed. The U.S. bond
market has generally declined, as fixed income investors became increasingly
concerned about the effects of rising interest rates.
      In the stock market, the performance of largecapitalization growth stocks,
which has driven the market's advance over the past few years, has begun to
moderate, and many previously out-of-favor value-oriented mid-cap and small-cap
stocks have rallied. At the same time, a healthy percentage of actively managed,
diversified portfolios have once again begun to outperform unmanaged stock
indices such as Standard & Poor's 500.

PRESIDENT'S LETTER

At OppenheimerFunds, we applaud the Fed's pre-emptive strike against inflation.
In our view, history has repeatedly demonstrated that most financial assets do
best in a low-inflation environment. What's more, we believe that the move to
higher interest rates should be temporary.
      One recent development is quite troublesome to us however: the increasing
popularity of "day trading" among individuals seeking to make fast money in a
volatile stock market. In our opinion, day trading is not investing, it is
gambling. Experience proves that without extensive research and analysis,
attempting to time short-term price swings is a fool's errand. Instead, we
continue to encourage investors to maintain a long-term perspective that is
measured in years, not days.
      Finally, while we remain alert to the potential impact of the Y2K issue,
we are encouraged by the progress made in addressing the matter. At
OppenheimerFunds, our shareholder accounting systems are already Y2K compliant,
and we have successfully participated in all required industrywide tests. We
intend to continue retesting our systems in order to help further protect
against any potential problems. After all, whether in our computer accounting
systems or the financial markets, managing risk is an important part of what
makes OppenheimerFunds The Right Way to Invest.

Sincerely,

/s/ James C. Swain           /s/ Bridget A. Macaskill

AN INTERVIEW WITH YOUR FUND'S MANAGERS

Q How did the Fund perform during the period?

A. During the fiscal year that ended September 30, 1999, the Fund delivered an
average annual total return of 2.78% for Class A Shares before deducting sales
charges. The 30-day standardized yield at September 30, 1999, was 5.43%,
compared to 4.61% one year earlier. Monthly dividend payments on Class A shares
declined slightly, from $0.05350 per share to $0.05120 per share, largely due to
an overall decline in interest rates during the 12-month period.

What happened to interest rates and the fixed income markets during the period?

Just before the Fund's 1999 fiscal year began, the Federal Reserve enacted the
first of three 0.25% cuts in its key interest rate. The fixed income markets had
been in turmoil for several months, due to economic and financial problems in
Asia and Russia. As the economic crisis spread worldwide, fears arose that the
U.S. economy might slip into a recession. By reducing interest rates throughout
the fall, the Fed indicated its willingness to help stabilize the economic
situation at home and abroad.
      As investors seeking high quality investments bid up prices on Treasuries,
the spread, or difference in yields, between U.S. Treasuries and other fixed
income securities (i.e., "spread products") widened considerably in August and
September 1998. But as the Fed continued to be supportive and investors regained
confidence, spread products reclaimed some of their performance over Treasuries
in October, November and December.

AN INTERVIEW WITH YOUR FUND'S MANAGERS

The fears of a U.S. recession proved unfounded. By January, it was clear that
our economy continued to expand at a very strong rate. Anticipating inflationary
pressures and higher interest rates, investors now demanded higher yields on
Treasuries. Treasury yields climbed, and spreads between Treasuries and
non-Treasuries quickly narrowed.

for investors."

[End Sidebar Text]

      In early 1999, world markets began to stabilize. The U.S. inflation rate
remained low, while consumer spending and corporate earnings continued to grow.
With the signs of worldwide recession fading, the Fed began reversing the
interest rate reductions it made in 1998, raising its key rate 0.25% in both
June and August. By September, the securities markets seemed to be preparing for
a third rate hike.

How did you adjust the Fund's holdings as interest rates changed?

Our extensive research on Treasury securities shows that the short to
intermediate part of the Treasury yield curve provides the greatest return per
unit of risk involved. In short, we believe this is the "sweet spot" on the
Treasury yield curve and provides superior long-term returns. Generally, we keep
our Treasury holdings within this range, moving to the short or long end of the
range based on our view of interest rate trends. This provides a measure of
price stability for the Fund, while the use of mortgage-backed securities (MBSs)
enhances both its yield and total return.

                 4        OPPENHEIMER LIMITED-TERM GOVERNMENT FUND


<PAGE>


MBSs are subject to prepayment risk, or the possibility that property owners
will refinance their mortgages, especially when interest rates fall. Due to this
risk and the uncertainty associated with it, MBSs offer higher yields than
Treasuries. They may outperform Treasuries when interest rates rise but provide
their best total returns when interest rates are stable.

[End Sidebar Text]

      At the start of the fiscal year, the Fund was underweighted in MBSs, which
was fortunate, since they generally underperform when rates decline. By October
and November, MBSs had become relatively inexpensive and offered attractive
return potential, so we steadily increased the MBS allocation to nearly 50% of
assets.

How did changing the allocation to MBSs impact the Fund?

MBSs were a major contributor to the Fund's performance. When interest rates
rose in January, our Treasury investments lost some value. Fortunately, we were
still focused on shorter-term issues, so the impact was minimized. And any
impact was offset by results in the MBS portfolio, which performed very well. We
owned short average maturity collateralized mortgage obligations (CMOs), which
have collateral to secure payment of interest and principal. Generally less
volatile than generic MBSs as rates change, these particular CMOs offer much
higher yields than comparable Treasuries.

AN INTERVIEW WITH YOUR FUND'S MANAGERS

After April, we moved the Fund's duration (a measure of sensitivity to interest
rate changes) to a relatively neutral position from a slightly defensive one. We
also trimmed our MBS holdings and began a period of "cherry picking." Despite
fairly predictable interest rates in recent months, mortgage-backed securities
have not done as well as might be expected. Although we do not foresee any major
problems from Y2K, corporations are issuing debt in advance of that event,
flooding the markets with an alternative to MBSs. The spillover effect has made
MBSs more volatile than the interest rate and economic situation warrant. For
this reason, we have held the Fund's MBS allocation below normal levels since
mid-summer while actively taking advantage of short-term anomalies in the
marketplace. For instance, we have purchased MBSs and CMOs whose prices were
depressed temporarily and traded them quickly when their prices rebounded.

[End Sidebar Text]

What is your outlook for the Fund over the coming months?

We believe a third interest rate increase is possible, even probable, before the
calendar year-end. However, it may be a non-event--simply the last step in
getting back to "business as usual." The markets have already factored in this
possibility. Investors also seem comfortable that the Fed has promised to
provide adequate liquidity to help the markets deal with any Y2K issues.

2. Standardized yield is based on net investment income for the 30-day period
ended September 30, 1999. Falling share prices will tend to artificially raise
yields.

                 6        OPPENHEIMER LIMITED-TERM GOVERNMENT FUND

We look for interest rates to remain in a relatively narrow range, which should
bode well for the Fund's MBS portfolio. In fact, we expect to increase our MBS
investments in the coming quarter. This should help to keep the Fund's income
strong while our emphasis on the shortest of intermediate Treasuries keeps its
value relatively consistent--just two of the reasons why Oppenheimer
Limited-Term Government Fund is part of The Right Way to Invest.

FUND PERFORMANCE

How has the Fund performed?

Below is a discussion, by the Manager, of the Fund's performance during its
fiscal year ended September 30, 1999, followed by a graphical comparison of the
Fund's performance to an appropriate broad-based market index and a sector
index.

      Management's discussion of performance. The first half of the fiscal year
that ended September 30, 1999, was a period of volatile interest rates, due to
worldwide economic issues, three Federal Reserve interest-rate reductions and
investor reaction to potentially higher inflation in the United States. Yield
spreads between Treasuries and other securities initially widened considerably
and then contracted rapidly. To protect the Fund against fluctuating interest
rates, we maintained a shorter-duration Treasury portfolio and selectively
purchased and sold short-term collateralized mortgage obligations and other
mortgage-backed securities.
      In contrast, the second half of the fiscal year saw a return to more
normal yield spreads and two widely anticipated Federal Reserve interest-rate
increases. Due to technical factors, including a larger-than-usual supply of
alternative fixed income investments, mortgage-backed securities as a whole did
not fare particularly well. During this period, the Fund selectively purchased
inexpensive MBSs that offered reduced prepayment risk and, therefore, less
volatility. These instruments provided important diversification for the Fund
and boosted its current and effective yields. The Fund's portfolio holdings,
allocations and strategies are subject to change.

      Comparing the Fund's performance to the market. The graphs that follow
show the performance of a hypothetical $10,000 investment in each class of
shares of the Fund held until September 30, 1999. In the case of Class A shares,
performance is measured over a 10-year period. In the case of Class B shares,
performance is measured from inception of the

                 8        OPPENHEIMER LIMITED-TERM GOVERNMENT FUND


<PAGE>


class on May 3, 1993. In the case of Class C shares, performance is measured
from inception of the class on February 1, 1995. In the case of Class Y shares,
performance is measured from the inception of the class on January 26, 1998. The
Fund's performance reflects the deduction of the maximum initial sales charge on
Class A shares, the applicable contingent deferred sales charge on Class B and
Class C shares, and reinvestments of all dividends and capital gains
distributions.
      The Fund's performance is compared to the performance of the Lehman
Brothers U.S. Government Bond Index and the Lehman Brothers 1-3 Year Government
Bond Index. The Lehman Brothers U.S. Government Bond Index is a broad-based
unmanaged index of U.S. Treasury issues, publicly issued debt of U.S. Government
agencies and quasi-public corporations and corporate debt guaranteed by the U.S.
Government. This index is widely used to measure the performance of the U.S.
Government securities market. The Lehman Brothers 1-3 Year Government Bond Index
is an unmanaged sector index of U.S. Treasury issues, publicly issued debt of
U.S. Government agencies and quasi-public corporations and corporate debt
guaranteed by the U.S. Government with maturities of one to three years. This
secondary index comparison is included to reflect the adoption by the Fund,
effective May 1, 1994, of the investment policy that the Fund will, under normal
circumstances, seek to maintain a dollar-weighted average portfolio effective
duration of not more than three years.
      Index performance reflects the reinvestment of dividends but does not
consider the effect of capital gains or transaction costs, and none of the data
in the graphs that follow shows the effect of taxes. The Fund's performance
reflects the effects of Fund business and operating expenses. While index
comparisons may be useful to provide a benchmark for the Fund's performance, it
must be noted that the Fund's investments are not limited to the securities in
the indices.

NOTES

In reviewing performance and rankings, please remember that past performance
does not guarantee future results. Investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than the original cost. The Fund's
performance may from time to time be subject to substantial short-term changes,
particularly during periods of market or interest rate volatility. For updates
on the Fund's performance, please contact your financial advisor, call us at
1.800.525.7048 or visit our website, www.oppenheimerfunds.com.

Total returns and the ending account values in the graphs include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown.

Class A shares of the Fund were first publicly offered on 3/10/86. The average
annual total returns are shown net of the applicable 3.50% maximum initial sales
charge. The Fund's maximum sales charge for Class A shares was higher prior to
2/23/94, so actual performance may have been lower.

Class B shares of the Fund were first publicly offered on 5/3/93. The average
annual total returns are shown net of the applicable contingent deferred sales
charges of 4% (1-year) and 1% (5-year). Because Class B shares convert to Class
A shares 72 months after purchase, the "life-of-class" return for Class B uses
Class A performance for the period after conversion. Class B shares are subject
to an annual 0.75% asset-based sales charge.

Class C shares of the Fund were first publicly offered on 2/1/95. The average
annual total returns are shown net of the applicable 1% contingent deferred
sales charge for the one-year period. Class C shares are subject to an annual
0.75% asset-based sales charge.

Class Y shares of the Fund were first publicly offered on 1/26/98. Class Y
shares are offered only to certain institutional investors under special
agreement with the Distributor.

An explanation of the different performance calculations is in the Fund's
prospectus.

FOOTNOTES TO STATEMENT OF INVESTMENTS

1. Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields upon the
current cost basis and estimated timing and amount of future cash flows.
These securities amount to $86,543,630 or 6.44% of the Fund's net assets as of
September 30, 1999.
2. When-issued security to be delivered and settled after September 30, 1999.
3. Principal-Only Strips represent the right to receive the monthly principal
payments on an underlying pool of mortgage loans. The value of these securities
generally increases as interest rates decline and prepayment rates rise. The
price of these securities is typically more volatile than that of coupon-bearing
bonds of the same maturity. Interest rates disclosed represent current yields
based upon the current cost basis and estimated timing of future cash flows.
4. Securities with an aggregate market value of $2,227,010 are held in
collateralized accounts to cover initial margin requirements on open futures
sales contracts. See Note 5 of Notes to Financial Statements.
5. For zero coupon bonds, the interest rate shown is the effective yield on the
date of purchase.

1. Significant Accounting Policies

Oppenheimer Limited-Term Government Fund (the Fund) is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's investment objective is to seek high
current return and safety of principal. The Fund's investment advisor is
OppenheimerFunds, Inc. (the Manager). The Fund offers Class A, Class B, Class C
and Class Y Shares. Class A shares are sold with a front-end sales charge on
investments up to $1 million. Class B and Class C shares may be subject to a
contingent deferred sales charge (CDSC). Class Y shares are sold to certain
institutional investors without either a front-end sales charge or a CDSC. All
classes of shares have identical rights to earnings, assets and voting
privileges, except that each class has its own expenses directly attributable to
that class and exclusive voting rights with respect to matters affecting that
class. Classes A, B and C have separate distribution and/or service plans. No
such plan has been adopted for Class Y shares. Class B shares will automatically
convert to Class A shares six years after the date of purchase. The following is
a summary of significant accounting policies consistently followed by the Fund.
- --------------------------------------------------------------------------------
Securities Valuation. Portfolio securities are valued at the close of the New
York Stock Exchange on each trading day. Listed and unlisted securities for
which such information is regularly reported are valued at the last sale price
of the day or, in the absence of sales, at values based on the closing bid or
the last sale price on the prior trading day. Long-term and short-term
"non-money market" debt securities are valued by a portfolio pricing service
approved by the Board of Trustees. Such securities which cannot be valued by an
approved portfolio pricing service are valued using dealer-supplied valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and that the quotes reflect current market value, or are valued under
consistently applied procedures established by the Board of Trustees to
determine fair value in good faith. Short-term "money market type" debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last determined market value) adjusted for amortization to maturity of any
premium or discount. Options are valued based upon the last sale price on the
principal exchange on which the option is traded or, in the absence of any
transactions that day, the value is based upon the last sale price on the prior
trading date if it is within the spread between the closing bid and asked
prices. If the last sale price is outside the spread, the closing bid is used.

- --------------------------------------------------------------------------------
Securities Purchased on a When-Issued Basis. Delivery and payment for securities
that have been purchased by the Fund on a forward commitment or when-issued
basis can take place a month or more after the transaction date. Normally the
settlement date occurs within six months after the transaction date; however,
the Fund may, from time to time, purchase securities whose settlement date
extends beyond six months and possibly as long as two years or more beyond trade
date. During this period, such securities do not earn interest, are subject to
market fluctuation and may increase or decrease in value prior to their
delivery. The Fund maintains segregated assets with a market value equal to or
greater than the amount of its purchase commitments. The purchase of securities
on a when-issued or forward commitment basis may increase the volatility of the
Fund's net asset value to the extent the Fund makes such purchases while
remaining substantially fully invested. As of September 30, 1999, the Fund had
entered into net outstanding when-issued or forward commitments of $25,098,958.
       In connection with its ability to purchase securities on a when-issued or
forward commitment basis, the Fund may enter into mortgage dollar-rolls in which
the Fund sells securities for delivery in the current month and simultaneously
contracts with the same counterparty to repurchase similar (same type, coupon
and maturity) but not identical securities on a specified future date. The Fund
records each dollar-roll as a sale and a new purchase transaction.
- --------------------------------------------------------------------------------
Repurchase Agreements. The Fund requires the custodian to take possession, to
have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of purchase. If the seller
of the agreement defaults and the value of the collateral declines, or if the
seller enters an insolvency proceeding, realization of the value of the
collateral by the Fund may be delayed or limited.
- --------------------------------------------------------------------------------
Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily to
each class of shares based upon the relative proportion of net assets
represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

1. Significant Accounting Policies  Continued

Federal Taxes. The Fund intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers to shareholders. Therefore, no
federal income or excise tax provision is required. As of September 30, 1999,
the Fund had available for federal tax purposes an unused capital loss
carryover of approximately $10,941,000, which expires in 2007.
- --------------------------------------------------------------------------------
Dividends and Distributions to Shareholders. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.
- --------------------------------------------------------------------------------
Classification of Distributions to Shareholders. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax
purposes. The character of distributions made during the year from net
investment income or net realized gains may differ from its ultimate
characterization for federal income tax purposes. Also, due to timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the fiscal year in which the income or realized gain was recorded
by the Fund.
      The Fund adjusts the classification of distributions to shareholders to
reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended September 30, 1999, amounts have been reclassified to reflect a
decrease in undistributed net investment income of $1,860,271. Accumulated net
realized loss on investments was decreased by the same amount.
- --------------------------------------------------------------------------------
Expense Offset Arrangements. Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Fund.
- --------------------------------------------------------------------------------
Other. Investment transactions are accounted for as of trade date and dividend
income is recorded on the ex-dividend date. Discount on securities purchased is
amortized over the life of the respective securities, in accordance with federal
income tax requirements. Realized gains and losses on investments and options
written and unrealized appreciation and depreciation are determined on an
identified cost basis, which is the same basis used for federal income tax
purposes. Dividends-in-kind are recognized as income on the ex-dividend date, at
the current market value of the underlying security. Interest on payment-in-kind
debt instruments is accrued as income at the coupon rate and a market adjustment
is made periodically.
      The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

year ended September 30, 1999, was 0.42% of average annual net assets for each
class of shares.

- --------------------------------------------------------------------------------
Accounting Fees. The Manager acts as the accounting agent for the Fund at an
annual fee of $12,000, plus out-of-pocket costs and expenses reasonably
incurred.

- --------------------------------------------------------------------------------
Transfer Agent Fees. OppenheimerFunds Services (OFS), a division of the
Manager, is the transfer and shareholder servicing agent for the Fund and other
Oppenheimer funds. OFS's total costs of providing such services are allocated
ratably to these funds.

- --------------------------------------------------------------------------------
Distribution and Service Plan Fees. Under its General Distributor's Agreement
with the Manager, the Distributor acts as the Fund's principal underwriter in
the continuous public offering of the different classes of shares of the Fund.

</TABLE>

      The Fund has adopted a Service Plan for Class A shares and Distribution
and Service Plans for Class B and Class C shares under Rule 12b-1 of the
Investment Company Act. Under those plans the Fund pays the Distributor for all
or a portion of its costs incurred in connection with the distribution and/or
servicing of the shares of the particular class.

                 30     OPPENHEIMER LIMITED-TERM GOVERNMENT FUND
<PAGE>

- --------------------------------------------------------------------------------
Class A Service Plan Fees. Under the Class A service plan, the Distributor
currently uses the fees it receives from the Fund to pay brokers, dealers and
other financial institutions. The Class A service plan permits reimbursements
to the Distributor at a rate of up to 0.25% of average annual net assets of
Class A shares. The Distributor makes payments to plan recipients quarterly at
an annual rate not to exceed 0.25% of the average annual net assets consisting
of Class A shares of the Fund. For the fiscal year ended September 30, 1999,
payments under the Class A Plan totaled $1,705,756, all of which was paid by
the Distributor to recipients. That included $125,039 paid to an affiliate of
the Distributor's parent company. Any unreimbursed expenses the Distributor
incurs with respect to Class A shares in any fiscal year cannot be recovered in
subsequent years.
- --------------------------------------------------------------------------------
Class B and Class C Distribution and Service Plan Fees. Under each plan,
service fees and distribution fees are computed on the average of the net asset
value of shares in the respective class, determined as of the close of each
regular business day during the period. The Class B and Class C plans provide
for the Distributor to be compensated at a flat rate, whether the Distributor's
distribution expenses are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.
      The Distributor retains the asset-based sales charge on Class B shares.
The Distributor retains the asset-based sales charge on Class C shares during
the first year the shares are outstanding. The asset-based sales charges on
Class B and Class C shares allow investors to buy shares without a front-end
sales charge while allowing the Distributor to compensate dealers that sell
those shares.
      The Distributor's actual expenses in selling Class B and Class C shares
may be more than the payments it receives from the contingent deferred sales
charges collected on redeemed shares and from the Fund under the plans. If
either the Class B or the Class C plan is terminated by the Fund, the Board of
Trustees may allow the Fund to continue payments of the asset-based sales
charge to the Distributor for distributing shares before the plan was
terminated. The plans allow for the carry-forward of distribution expenses, to
be recovered from asset-based sales charges in subsequent fiscal periods.

Distribution fees paid to the Distributor for the year ended September 30,
1999, were as follows:

5. Futures Contracts

The Fund may buy and sell futures contracts in order to gain exposure to or to
seek to protect against changes in interest rates. The Fund may also buy or
write put or call options on these futures contracts.
      The Fund generally sells futures contracts to hedge against increases in
interest rates and the resulting negative effect on the value of fixed rate
portfolio securities. The Fund may also purchase futures contracts to gain
exposure to changes in interest rates as it may be more efficient or cost
effective than actually buying fixed income securities.
      Upon entering into a futures contract, the Fund is required to deposit
either cash or securities (initial margin) in an amount equal to a certain
percentage of the contract value. Subsequent payments (variation margin) are
made or received by the Fund each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses. The Fund may recognize a realized gain or loss when the contract is
closed or expires.
      Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. The Statement of Assets and Liabilities reflects a receivable
and/or payable for the daily mark to market for variation margin.
      Risks of entering into futures contracts (and related options) include
the possibility that there may be an illiquid market and that a change in the
value of the contract or option may not correlate with changes in the value of
the underlying securities.

As of September 30, 1999, the Fund had outstanding futures contracts as follows:

6. Bank Borrowings

The Fund may borrow from a bank for temporary or emergency purposes including,
without limitation, funding of shareholder redemptions provided asset coverage
for borrowings exceeds 300%. The Fund has entered into an agreement which
enables it to participate with other Oppenheimer funds in an unsecured line of
credit with a bank, which permits borrowings up to $400 million, collectively.
Interest is charged to each fund, based on its borrowings, at a rate equal to
the Federal Funds Rate plus 0.35%. Borrowings are payable 30 days after such
loan is executed. The Fund also pays a commitment fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of
0.0575% per annum.
     The Fund had no borrowings outstanding during the year ended September 30,
1999.

INDEPENDENT AUDITORS' REPORT

================================================================================
To the Board of Trustees and Shareholders of
Oppenheimer Limited-Term Government Fund:

We have audited the accompanying statement of assets and liabilities, including
the statement of investments, of Oppenheimer Limited-Term Government Fund as of
September 30, 1999, the related statement of operations for the year then
ended, the statements of changes in net assets for the years ended September
30, 1999 and 1998, and the financial highlights for the period October 1, 1994,
to September 30, 1999. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.
      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
September 30, 1999, by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other auditing procedures.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
      In our opinion, such financial statements and financial highlights
present fairly, in all material respects, the financial position of Oppenheimer
Limited-Term Government Fund as of September 30, 1999, the results of its
operations, the changes in its net assets, and the financial highlights for the
respective stated periods, in conformity with generally accepted accounting
principles.

FEDERAL INCOME TAX INFORMATION  Unaudited

================================================================================
In early 2000, shareholders will receive information regarding all dividends and
distributions paid to them by the Fund during calendar year 1999. Regulations of
the U.S. Treasury Department require the Fund to report information to the
Internal Revenue Service.
       None of the dividends paid by the Fund during the fiscal year ended
September 30, 1999, are eligible for the corporate dividend-received deduction.
       The foregoing information is presented to assist shareholders in
reporting distributions received from the Fund to the Internal Revenue Service.
Because of the complexity of the federal regulations which may affect your
individual tax return and the many variations in state and local regulations, we
recommend that you consult your tax advisor for specific guidance.
